ience of vsuch ovens particularly when employed in the production of confectionery vand other goods requiring variable periods of baking.

The invention comprises the combination with a'baking chamber having a circuitousp ly larranged conveyor and heating `elements thereimef may be placed upon the conveyor and withdr'awn therefrom `at various points or po-y sitions in its course through the chamber, and so that goods requiring subjection to .the baking heat for varying 'periods and/or from the lconveyor a at l2 a plan Iingaccess under varying conditions as toa steam or dry atmosphere and otherwise, maybe in simultaneous transit throughthe oven there-- by enabling bakings under such varying conditions to be eiected concurrently.

Referring to the two accompanying sheets of explanatory drawings:

Figure l is a sectional elevation,

with half of the top removed, and Figure 3 an end view showing, in dia ram'- matic form, an oven in accordance wit this invention.

The samel reference letters in the dig 'another batch maybe simultaneously baking or subjected, in thel ferent views indicate the same or similar parts.

vv)n carrying the invention into effect, there Ip is provided at the vfront or 4operative end or side of the oven a plurality of doors givtothe baking chamber and such of the goods being readi-l an as to permit l' laced upon and with rawn conveniently p in its circuitous course ber.- 4Such doors 'as b, c, are preferably arranged in pairs and,` as shown, at Figure 1, in a V or angular `disposition and projecting towards the interior of the-chamber,

' osition to place the' goods 'upon` and withdraw them from the conveyor `i at different pointsin its course. The lo# cation of the said pairs of doors lor duplex doors is such that though there is butja little actual. distance between the transit of the the other represents out change vor conveyor a lfrom one to a considerable proporj means whereby from the one position on the exterior of the chamber goods Figure different positions. through the cham-` the said points,A

With the oven equipped as aforesaid, the goods to be subjected to the maximum baking period afforded with a given speed ot' the conveyor, are placed upon and removed from the conveyor at one and the same door; they are thus carried ythrough the vcomplete ath or circuit of the conveyorl through the baking chamber. For a shorter baking period the goods are inserted on the conveyor through one door, as for example' the door c, and withdrawn through the other door b.` A still shorter baking period will the .doorb to the door o is shorter than its Apath yor course from thedoor o to the door b.

The upper or other conveyors may pass through a steam laden lengths or'runs of the lbe obtained if the goods are inserted on the atmosphere whilst the remainder may pass through a dry atmosphere, such atmosphere being provided for within thebaking chamber in any ordinary manner, as for example by means of a steam inlet -pipe at 2 and an outlet pipe at 3. Thus whilst one batch of oods are being baked in adry .atmosphere d conveyor, either as regards its rate of move mentor otherwise, or of any gther part of the oven.

The heating elements d may be of any suitable type', either gas, steam or electric, and rovided with ordinary-means for heat. regu ation. As illustrated at Figures. 1 and 2, the .heating elements d are isposed be h tween the respective straightlengths or. runs 'of the conveyor a.

.Theconveyor is of the pe with suspended shelves or known chain t I electrically or otherwise optrays as f, an

erated `through mechanism em loyed for suehvservices. In the example il ustrated the electric motor g transmits power through belt h to gear box z' and thence through belt j and gear wheels t -l y the usualy speed changing i to the-conveyor driving Wheel l. Suitable guide wheels as m are arranged Within the as n for the conveyor a. Any ordinary provision is made for keeping the conveyor at the required tension.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In baking ovens, the combination comprising a baking chamber, a conveyor passing inv a circuitous course through said chamber, heating elements disposed between the respective straight lengths or runs' of the conveyor, an angular projection from the wall of the baking chamber into the interior of the latter, and a door in each of the sides of said projection said doors giving access to the conveyor at various positions in its circuitous course from the one position on the exterior of the chamber. baking chamber and also supporting tracks 2. In baking ovens, the combination comrismr a bakmoF chamber a conve or assa: n a

mg in aY circuitous course through said chamber, heating elements disposed between the respective straight lengths or runs of the conveyor, an angular projection from the Wall of the baking chamber into the interior of the latter, a door in each of the sides of said project-ion, said doors giving access to the conveyor -at various positions in its circuitous course from vthe one position on the exterior of the chamber, and means providing steam laden and dry atmospheres for said course.

In testimony whereof I have name to this Specification.
